Molly Gold Project Drilling Update

Advancing Towards Resource Growth in a Prime Gold Jurisdiction

Jangada Mines plc (AIM: JAN), a Brazil-focused natural resource development company, is pleased to announce a positive update on the ongoing diamond drilling campaign at the Molly Gold Project ('Molly' or the Project') in the Tapajós Gold Province of Pará State in Brazil.

Overview:

·    13 holes drilled for a total of 2,076 metres primarily targeting the high-grade Molly 1 & 2 targets

·    Highly encouraging indications from step-out drilling has reinforced district-scale prospectivity

·    All holes drilled contained quartz vein and/or disseminated sulphides, the host for gold in this style of mineralisation

·    44 samples sent to labs with assay results expected mid-April

·    Expectation remains to materially build on existing JORC resource of 130k oz Au

·    Minimum drilling requirements of 2,000 metres successfully met, Company to exercise option to acquire 100% of the 6,656.2-hectare project

·    Completion of Phase 1 drilling expected early April, Phase 2 of drilling and geological work to commence shortly thereafter

·    Fully funded for the next phase of exploration

Paulo Misk, CEO of Jangada Mines, commented: "We are delighted with the initial findings of the drill campaign at Molly, where every hole has intersected quartz veining and/or disseminated sulphides, the characteristic host for gold in this style of mineralised system. The Molly 2 target has returned the correct geological signatures, indicating continuity of mineralisation and highlighting the potential to significantly grow the 130,000 oz JORC resource in the near term."

"With all holes returning encouraging geological signatures and intersections, we believe there is a clear pathway to expanding the resource through continued drilling. If the geology and grades continue to deliver, the project has the potential to evolve into a much larger gold system, underpinned by multiple targets and broader district-scale prospectivity."

"We are excited by the progress made and look forward to maintaining strong news flow in the coming weeks as assay results are received and the next fully funded phase of exploration gets underway."

Drilling Campaign:

The campaign at Molly focused on infill drilling at the highly prospective Molly 1 target to upgrade the historic JORC 130,000 oz Au Inferred Resource. Step-out drilling was also undertaken to the west, including the Molly 2 target, as well as to the east, with early indications suggesting substantial extensions in both directions.

To date 13 holes have been drilled for a total of 2,076 metres, with hole depths ranging from 150-250 metres. Due to positive core retrieved, the programme has been widened to approximately 2,480 metres, exceeding initial plans by 480 metres. Importantly and highly encouragingly, all holes drilled to date contained quartz vein and/or disseminated sulphides. Furthermore, the drilling of the western extension and Molly 2 delivered highly encouraging geological indicators and intercepts of massive sulphides, reinforcing confidence in the scale and quality of the mineralised system. The balance of the Phase 1 drilling campaign is expected to be completed in the first week of April.  Given positive results the Board has decided to execute the exercise of its option to acquire the Project (see below).

A total of 44 samples have been submitted for assay, with results expected in mid-April. These results will provide critical insight into the mineral composition of the project, potentially building significantly on the initial declared JORC inferred resource of 130k oz Au from 2.1Mt @ 2g/t at a 0.5 g/t cutoff and guide the Company in its next phase of drilling.  The intention is to publish an updated resource number as soon as possible. 

Underscoring the potential of the system, the historic 2,857 metre 19-hole diamond drilling programme has previously confirmed the presence of a robust high-grade, near-surface epithermal primary gold system at shallow depths: Grades included 3.0m @ 14.4g/t, 5.07m @ 8.6g/t, 6.5m @ 10.5g/t and 1m @ 200 g/t.

Project Development:

Once all the drill results have been returned and evaluated, the Company will immediately plan and execute extensive exploration work to further ascertain the potential of the immediate Molly 1&2 target zones and quantify the extent of this mineralised structure as well as the wider licence. The medium-term aim is to define a multi-pit operation with work including further drilling at the Molly 2 prospect, metallurgical test work, and preliminary economic assessments. The Company is funded for these programmes.

In May, the Company aims to initiate further mapping, geophysical, geochemical studies and trenching at selected targets. Geophysical work is currently anticipated to be completed up to September 2026 and will play a key role in identifying new drill targets across the broader area, including the Boomerang zone.  Boomerang is an area north of Molly 1 where extensive garimpeiros work has been conducted.  The extent of the workings highlights the potential of an enlarged mineralised system either below or within the elevated higher ground either side of the workings area.

The Company remains well funded to complete the next stage of its exploration activities.  Overall, the Board believes there is a clear pathway to growing the resource through continued drilling and exploration. If the geology continues to deliver positive results, the project has the potential to evolve into a much larger gold system, supported by multiple targets and broader district-scale potential.

BGold Acquisition Option:

As per the initial agreement announced on 9 February 2026 an exclusive option was signed with BGold to acquire a 100% interest in the Molly Project. The option terms comprised staged initial cash and share payments, together with work commitments, aligned with exploration success, with additional consideration payable in cash and shares upon the definition of mineral resources. The Vendor will retain a 2.0% 'NSR royalty, with any NSR advance deferred if production is delayed. Jangada will act as operator during the option period and will fund all exploration and development activities.

The initial drilling obligation and option right terms have now been fulfilled, being the completion of a minimum of 2,000 metres of diamond drilling on the Project. Accordingly, a definitive agreement is being finalised and subject to the necessary AIM regulatory approvals being obtained to enter into it on the terms intended, it will involve an initial cash payment of US$100,000 to BGold and the issuance of US$250,000 in Jangada shares. Any shares issued to the vendor will be subject to a 1-year hard lock up from the date of issuance. Further announcements will be made as and when appropriate.

Qualified Person Signoff:

The resource information in this announcement has been reviewed by Mr. Emerson Ricardo Re who is a senior professional geologist with 25 years of experience in the mining industry, which is relevant to the style of mineralisation and type of deposit under consideration and to the activity which he has undertaken to qualify as a Competent Person as defined in the 2012 edition of the JORC Code. Mr. Re also meets the requirements of a competent person under the AIM Note for Mining, Oil and Gas Companies. Mr. Re has no economic, financial or pecuniary interest in the Company, and he consents to the inclusion in this document of the matters based on his technical information in the form and context in which it appears.
